16. SUBSEQUENT EVENT

In July 2020, the Compensation Committee granted 43,000 MPSUs to the executive officers and 2,000 MPSUs to certain key employees, which represent a target number of shares that can be earned based on the achievement of both market and performance conditions (“2020 MPSUs”).  The maximum number of shares that an employee can earn is 500% of the target number of the 2020 MPSUs. The market conditions consist of the achievement of five stock price targets ranging from $260 to $300 with a performance period through July 20, 2023, and the performance condition consists of the achievement of one business operating goal with a performance period through December 31, 2021.  Upon achievement of the market and performance conditions, 75% of the 2020 MPSUs will vest on July 20, 2023 and 25% of the 2020 MPSUs will vest on July 20, 2024.  All vested shares will be subject to a post-vesting sales restriction period of one year.
